[Notice] Master Key Level Limit

Sometimes nexon just make no sense at all. Just like they put a 7 day limit for the account to purchase NX.

They do that so people can't as quickly buy paypal nx -> buy gachapon/mesos -> transfer to another account -> get a refund -> empty account gets banned. I'm not sure exactly how they do it, but that's the gist of it. It's also one of the reasons that the level 16 block is there on trading over 1mil a day.
